  • the known fastening device enables a pretensioning force of a rail clamp to be changed.
  • Such a change or setting of the pretensioning force of the rail clamp is achieved in that a semicircular profile serving as a support chuck for the guide rail can have different thicknesses.
  • From the DE3010826 a rail foot holder according to the preamble of claim 1 is known.
  • the elevator rails can be attached directly or indirectly to a building wall.
  • Such an elevator rail can serve, for example, as a guide rail for an elevator car or a counterweight of the elevator installation.
  • Such elevator rails usually extend over the entire travel path of the elevator, which in many cases can approximately correspond to the height of the building.
  • the elevator rails are so firmly attached in the building that lateral managers can be safely picked up.
  • the building height can change over time. There are several possible reasons for this. For example, a building can shrink after its completion as a result of concrete drying out and building settlement. Changes in building height can also be caused by temperature changes and solar radiation.

  • the rail foot holder can also be manufactured and sold independently of a rail or other components of an elevator system.
  • the rail foot holder is designed in such a way that an improved arrangement and / or assembly of the rail is made possible with regard to a specific arrangement of the rail.
  • an improved setting can take place with regard to fastening the rail without play, for example.
  • This makes it possible in particular to compensate for manufacturing tolerances of the rail, which can specifically affect a material thickness of a rail foot.
  • the material thickness of the rail foot can vary from rail section to rail section. If such rail sections are then joined together to form the rail, then a slightly different adjustment of the holding dimension may be required in each section.
  • This setting can be carried out in a particularly simple manner by a fitter when the rail is installed in the elevator shaft.
  • a method for fastening a rail of an elevator system in an elevator shaft by means of at least one rail foot holder according to the invention can be specified, the contact body being arranged in a stationary manner in the elevator shaft, with a first side part of the rail foot between the holding head of the holding device and that through the contact body predetermined contact plane is arranged, and wherein the holding head is rotated to reduce the holding dimension between the holding head of the holding device and the contact plane about the axis of rotation of the holding device.
  • first side part and second side part of the rail foot are used here to denote the two side parts of the rail foot, without this being intended to specify which of the two side parts is designated as the first or second side part.
  • the rail foot can be modified so that the two side parts of the Rail foot are just referred to in an interchanged manner as the first and second side part. In terms of design, this can correspond to a reflection of the rail foot holder on a suitable construction plane. In principle, however, mirror-symmetrical designs of the rail foot holder are also conceivable in this regard. The same applies to the terms holding device and further holding device or first and second holding device.
  • a special feature of the proposed embodiment is that the holding head of the holding device can be adjusted to the generally toleranced dimensions of the rail foot without dismantling the holding device, which is referred to in the context of this application as "setting without disassembling".
  • "fastening without dismantling” is possible in that, in a possible further development, the holding device can be infeed or brought closer to the rail foot, which can be achieved, for example, by a suitable elongated hole.
  • an embodiment can be implemented in an advantageous manner in which both the setting without dismantling and the fastening without dismantling allow the holding head to be locked or fixed in the desired position by a single assembly step, for example tightening a screw is. Possible designs for setting without dismantling and for fastening without dismantling are also explained in further detail below and with reference to the description of the figures.
  • the holding head of the holding device can be rotated into the fastening position in the direction of rotation about the axis of rotation of the holding device for an adjustment serving to reduce the holding dimension. Furthermore, it is advantageous that the holding head of the holding device is rotated in the direction of rotation about the axis of rotation of the holding device into the fastening position during the setting, which serves to reduce the holding dimension. It can be adjusted without dismantling.
  • the holding head can be rotated about the axis of rotation into a fastening position in a further direction of rotation oriented counter to the direction of rotation in a setting serving to reduce the holding dimension, in particular when setting without dismantling, and that the side of the Holding head in a further fastening area extending in the further direction of rotation around the axis of rotation, where an at least indirect contact between the holding head and the first side part of the rail foot is made possible, is designed with a slope opposite to the further direction of rotation.
  • the fitter can reduce the holding measure when making adjustments, regardless of whether he is turning the holding head in the direction of rotation or in the other, namely further, direction of rotation for the purpose of adjustment.
  • the fitter can choose the most ergonomically favorable direction of rotation for both the right and the left hand.
  • the size and configuration of the holding head, in particular on its side facing away from the contact plane can be designed in such a way that, for example, advantageous gripping with a glove is made possible.
  • the holding device can be adjusted relative to the base body in such a way that a distance between the axis of rotation of the holding device and a further holding device, between which the rail foot can be fastened, can be changed.
  • the rail with its rail foot can be positioned between the two holding devices, then the holding device can be adjusted relative to the base body so that the distance between the axis of rotation of the holding device and the further holding device is reduced until the desired fastening position for the axis of rotation is reached, and then the holding head is rotated about the axis of rotation until the appropriate holding dimension is set.
  • the contact body has an elongated hole for this purpose, in which a bolt of the holding device is guided. This configuration then enables the holding device to be adjusted relative to the contact body.
  • the holding head of the holding device has an end face which faces the contact body and can be acted upon against the contact body by means of a fastening means of the holding device in order to fix the holding head relative to the contact body.
  • a fastening means can, for example, have a screw bolt which is fastened to the contact body, for example by means of a nut and a washer.
  • the screw bolt also serves as a bolt which is guided, for example, in an elongated hole in the contact body, in order to adjust the holding device allow relative to the plant body.
  • the face of the holding head of the holding device facing the contact body is designed as a structured face.
  • the structured end face can support the function of a fixation, since the influence of dirt, liquids, such as oil, and the like is reduced.
  • such grooves are designed as grooves extending radially to the axis of rotation of the holding device in the end face of the holding head facing the contact body.
  • grooves in particular grooves running radially to the axis of rotation, can also be combined with other structural elements on the end face in order to form a structured end face.
  • the structured end face is preferably designed in such a way that the end face of the holding head claws with the contact body when it is fixed or screwed tight. This prevents unintentional twisting of the holding head in the assembled state.
  • These grooves which run radially to the axis of rotation of the holding device and can serve to design the structured end face, meet this criterion.
  • a further holding device is provided and that a further holding device or an axis of rotation of the further holding device is arranged in a stationary manner on the contact body.
  • the holding device is adjustable relative to the contact body in such a way that the axis of rotation of the holding device can be adjusted relative to the contact body. If the further holding device needs to be positioned relative to the rail, this can be achieved in an advantageous manner by adjusting the contact body relative to a fastening body.
  • the further holding device is then first brought into the desired position in the elevator shaft.
  • the contact body can then be fixed in its position, which is made possible, for example, by a corresponding attachment to the attachment body.
  • the holding device can then be adjusted relative to the further holding device.
  • a holding head of the holding device and a holding head of the further holding device can then be adjusted.
  • a further holding device which has a holding head, wherein a second side part of the rail foot can be arranged between the holding head of the further holding device and the system level for fastening the rail, with a further holding dimension between the holding head of the further holding device and the contact level to compensate for tolerances of the second side part when fastening the rail of the rail foot can be changed, the holding head of the further holding device being rotatable in a direction of rotation about an axis of rotation of the further holding device into a fastening position when the further holding device is adjusted to reduce the further holding device, and one side of the holding head of the further holding device facing the contact plane in at least one in the direction of rotation about the axis of rotation of the holding device extending fastening area, at which an at least indirect contact between the holding head of the further holding device and the second side part of the rail foot is enabled i st, is designed with a slope opposite to the direction of rotation.
  • This configuration enables, for example, assembly steps according to which the rail foot is fastened on both sides at least essentially without play. It is also conceivable here that the holding dimension and the further holding dimension differ if this is necessary in the respective application, in particular due to different tolerances on the rail foot.
  • the holding head of the holding device or the holding head of the further holding device is designed on the side facing the contact plane in the at least one fastening area with a continuous slope in the direction of rotation or in the further direction of rotation.
  • the gradient does not experience any sudden change.
  • This configuration can thus relate to the holding head of the holding device and / or the holding head of the further holding device.
  • this can refer to only one or only the single fastening area or, if two fastening areas are provided, to both fastening areas.
  • a preferred embodiment of the incline, which does not change abruptly, consists in a continuously running incline. Different configurations are conceivable here.
  • the slope can be designed in such a way that the holding dimension changes linearly with the angle of rotation when rotating in the direction of rotation or in the further direction of rotation.
  • a fastening body which can be fastened in a stationary manner in the elevator shaft, and that the contact body can be connected to the fastening body. It is also advantageous here if the contact body can be connected to the fastening body in several possible connection positions. Discrete and / or continuous adjustment options can be implemented here. After the fastening body has been fixed in place, this then enables the position of the contact body to be advantageously adapted to the desired position specified for fastening the rail.
  • a cylinder jacket-shaped sliding surface is provided on the holding head or the further holding head, on which contact between the first side part or the second side part of the rail foot and the holding head is enabled for guiding the rail foot when the rail is attached. If, for example, there are relative changes in length between the rail and the building, a longitudinal compensation along the extent of the rail is required, which is held by the rail foot holder. At the same time, however, the rail should also remain movable relative to the rail holder along its extent. In particular, it makes sense here to avoid the build-up of mechanical stresses along the extension of a rail. In addition to an essentially play-free, but practically powerless fastening implemented via the holding dimension or the further holding dimension, this is made possible by reducing the holding friction between the holding head and the rail.
  • the equal surface is formed on a reduced-friction coating of the holding head or of the further holding head, which, among other things, reduces the relevant static friction.
  • an at least approximately hollow-cylindrical sliding ring is mounted on the sliding surface of the holding head or of the further holding head. In this case, contact between the first side part or the second side part of the rail foot and the sliding ring can then be made possible for guiding the rail foot.
  • the respective holding dimension can be set precisely according to a local rail foot thickness.
  • rail tolerances in particular tolerances on the side parts of the rail foot, can be absorbed.
  • There is also a lateral delivery for example, by means of a lateral elongated hole in the contact body.
  • a lubricant, a sliding layer and / or (in the lateral direction) a sliding ring can be provided on any contact or contact surfaces. In this way, in particular, a length compensation that occurs with a delay and indefinitely in time and then takes place in a jerk, so to speak, is avoided.
